after reverse

RE bids 2NT to show 7- HCP. If OP holds extras, she bids normally, else, she bids 3♣, RE passes, or bids her suit. 

Rule:   RE's rebid on level 2 (if possible) shows (sub)minimal strength. Rebid over 2NT shows 5+card suit and invitattion. Jump rebid shows 6+ card suit and GF strength

after we double opp's W2M bid. 

Double shows 11+ HCP with ideal distribution, more if distribution is more inadequate. Double shows 14+ HCP if 2M was intermediate.

If we have a hand that would like to have bid 2NT but without the sort of trump holding to

pass for penalties, then we go to 3NT via the appropriate route.
